Somehow, I missed this and haven’t used it until yesterday – GitHub markdown syntax highlighting:
Code blocks can be taken a step further by adding syntax highlighting. In your fenced block, add an optional language identifier and we’ll run it through syntax highlighting. For example, to syntax highlight Ruby code:
```ruby require 'redcarpet' markdown = Redcarpet.new("Hello World!") puts markdown.to_html ```We use Linguist to perform language detection and syntax highlighting. You can find out which keywords are valid by perusing the languages YAML file.
